Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a so-called "one-shottle bottle" cap mainly used for shochu or sake containers. The present invention relates to a structure of a combination cap which prevents "injury" at the time of removal, which is often a problem at the time of opening, and also has a pilfa proof performance.

[0002]

2. Description of the Related Art Conventionally, a shochu bottle filled with shochu or sake is composed of two parts, an inner stopper and an outer stopper. It is configured to be fitted to the bottle and to keep the contents with honey and to be re-closable. On the other hand, the outer stopper is made of a thin-walled aluminum, and the outer stopper is formed in a tubular shape slightly larger than the opened one, and after the contents are filled in the filling step and the inner stopper is stoppered. It is used so that it is covered with a bottle bottle, wound around a circumferential groove provided on the side surface of the bottle bottle, closed and fixed.

[0003] When opening the cap, the consumer who purchases the one-shoulder bottle raises a cut portion provided upward from the lower end of the outer plug with a finger or the like to pinch a part of the cut portion. Remove the outer plug while pulling the cut in the outer peripheral direction and use.

[0004] The removal of the outer plug is difficult to cut because the thin aluminum metal is torn, and the cut is sharp and often causes injuries such as cutting of a finger. There is a demand for improvement. In addition, a certain amount of force is required to cut through the metal, and it has been a potential problem that it is difficult for a weak woman to open the bag smoothly.

On the other hand, there is also a variation in the inner diameter of the bottle and a variation in the cap of the inner stopper, and there is a tendency that the sealing property must be emphasized even when the bottle is re-opened. In many cases, the relationship is set to be hard, and as a result, there is also a problem that the inner plug is difficult to remove.

[Problems to be solved by the invention]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned various problems at the same time and, naturally, satisfies the pill proof property, and does not cause any injuries by cutting a finger, which makes it extremely easy to open the cap. It has been completed to provide.

[Means for Solving the Problems]

[0007] In order to solve the above-mentioned problems, a combined cap according to the present invention is a combined cap formed by integrating an upper cap and a lower cap. A tamper-evidence band portion which is connected to at least three upper and lower positions by at least three easy-to-cut bridges and has a tearing knob on a part of the circumference, and covers the entire outer peripheral surface of the lower cap below the tamper-evident band portion. A lower cap cover portion having a projection formed on the inner surface and engaging with a circumferential groove formed on the side surface of the bottle at a position below the curl portion of the lower cap on the inner surface,
At the center of the lower surface of the top surface, a caulking tube for connecting to the lower cap is formed so as to hang down, and a pressing portion for pressing the vicinity of the center of the top portion of the lower cap around the caulking tube is formed. An upper cap made of a resin which is formed so as to hang down on the lower surface of the surface and provide a gap between the lower cap and an upper cap provided with a swaging hole at the center which can penetrate a swaging tube which is hung from the upper cap. And a curl portion is formed so that its lower end is engaged with the circumferential groove on the side surface of the bottle, and at least three slits are provided. Formed of a metal side cap formed on the inner surface thereof, and a resin packing member loaded on the inner surface thereof. The upper cap is placed concentrically on the lower cap, and the caulking cylindrical shape of the upper cap is formed. Penetrate through the caulking hole of the lower cap It is characterized in that the Jo of the lower end crimped.

Here, the cap may be made of a resin, but the upper cap may be made of a resin, but it is preferable that the upper cap be made of polyethylene or polypropylene. The lower cap may be any metal as long as it has elasticity. Preferably, the lower cap is selected from tin, stainless steel, or hard aluminum. The packing member loaded on the inner surface of the top portion of the lower cap may be a sheet-like member having a property of being slightly deformed when pressed, for example, a PET high sheet or a compression sheet generally used for an aluminum PP cap. It's like a cork sheet.

First, the structure of the upper cap is such that the bridge connecting the tamper-evidence band portion and the top surface and the tamper-evidence band portion and the lower cap cover portion provided at the lower end of the outer periphery of the top surface stabilizes the capping. At least three or more are required, but it is preferable to form about six to eight at equal circumferential intervals. It is preferable that the thickness is about 1 mm and the width is 0.3 to 2 mm in order to easily cut with a small force. Also, instead of being formed by intermittent bridges, it may be formed in a continuous band shape having a thickness of about 0.5 mm and easy to cut. Here, on the inner surface of the lower cap cover portion, there is provided a projection which engages with a circumferential groove formed on the side surface of the bottle at a position below the curl portion. Further, the side wall of the lower cap is inwardly concave at the horizontal position of the bottle top, and is formed in such a manner that the projection on the inner surface of the lower cap cover engages from the outside.

The caulking cylinder provided for connection with the lower cap may have any known shape. However, when the caulking tube is fitted into the through hole of the lower cap and caulked, the upper cap and the lower cap are horizontally positioned. It is sufficient if the fitting degree is such that it does not shift by 1 mm or more in the direction. It is preferable that the pressing portion is as close as possible to the center of the top panel, but it is sufficient that the pressing portion is provided within half of the abbreviated top portion of the cap in the radial direction. In addition, although both the crimping cylinder and the holding portion are preferably cylindrical in configuration, they may be intermittently cylindrical. The gap between the holding portion and the lower cap is made larger than the gap between the bridge of the upper cap. After mounting, it is prevented from being opened even if force is applied from the upper cap during handling such as transportation.

Next, the structure of the lower cap is such that a caulking hole for integrating the upper and lower caps is formed at the center of the top portion by penetrating the caulking cylindrical shape of the upper cap, and a circumference near the outer periphery of the top portion is formed. A downwardly convex portion is provided on a circumference corresponding to a substantially central portion of the thickness of the bottle above, and the convex portion is brought into contact with the packing member. When the cap is mounted by engaging with the peripheral groove of the above, the packing member and the bottle top face come into close contact with each other due to the elasticity of the metal of the lower cap, thereby maintaining airtightness.

A plurality of slits are provided from the side wall portion to the curl portion of the lower cap, and when the top portion is pressed to form a concave shape, the side wall portion is umbrella-shaped with the convex portion as a fulcrum due to the elasticity of the material of the cap. The cap is disengaged from the peripheral groove of the bottle opening and the curl portion is released. It is sufficient that at least three or more slits are provided, but it is desirable to provide eight to twenty-four slits on the circumference of the side wall part. At this time, even if the user removes the lower cap cover by holding it, there is no need to worry about cutting his / her fingers with a slit. In a state where the engagement between the circumferential groove and the curl portion is released, the diameter of the lower cap cover portion is set such that the diameter of the side wall portion expanding outward is not extremely larger than the diameter of the lower cap cover portion. A gap is provided between the part and the side wall part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partial sectional view showing a typical embodiment of the present invention, and shows a state in which a combination cap of the present invention is attached to a bottle 4 of a single bottle. Reference numeral 1 denotes an upper cap formed of polypropylene, which is connected to a lower end of the outer periphery of the top surface 11 by a plurality of bridges 15.
The lower portion also includes a tamper-evident band 12 connected by a plurality of bridges 15, and a tearing knob 12 a is provided at one end of the tamper-evident band 12 so as to be able to be taken out. A lower cap cover 27 is formed below the bridge 15 so as to cover the side wall 23 of the lower cap 2. Further, on the inner surface of the lower cap cover portion 27, a projection portion 28 is provided below the curl portion 24 and engages with a circumferential groove 41 provided on the side surface of the bottle opening 4. Furthermore, the side wall portion 23 of the lower cap 2 has a concave shape inward at the horizontal position of the bottle top, and is formed in a state where the projection 29 on the inner surface of the lower cap cover portion 27 engages from the outside. ing. On the lower surface of the top surface 11, a crimping tubular portion 13 and a concentric holding portion 14 are formed in the center of the crimping tubular portion 13 in the vicinity of the crimping tubular portion 13.

Reference numeral 2 denotes a lower cap made of tinplate. The lower cap 2 is provided with a caulking hole 22 at the center of the top 21 through which the caulking tubular portion 13 hanging from the upper cap 1 penetrates. A convex portion 26 is formed downward so as to be located substantially at the center of the thickness of the bottle 4 in the vicinity. A side wall 23 is provided from the outer periphery of the top 21 and provided with a plurality of slits 25 at equal intervals. A lower end of the side wall 23 is formed with a curl 24 and formed on the side surface of the bottle 4. And engages with the peripheral groove 41. A packing member 3 made of PET manufactured by Nippon High Seat Industry Co., Ltd. is loaded below the top 21 inside the lower cap 2 so as to abut on the projection 26.

The curl portion 24 extends from the side wall portion 23 of the lower cap.
The packing member 3 is loaded in the lower cap 2 and when the cap is attached to the bottle 4, the lip of the bottle 4 presses the packing member 3 and cuts into the packing member 3 to keep the bottle airtight. It is formed in such a dimensional relationship as follows.

The upper cap 1, the lower cap 2 and the packing member 3 of the present invention are manufactured in different processes and are combined in the form shown in FIG.

Next, the method of mounting the combination cap of the present invention on the bottle in the filling step is as follows: the combination cap of the present invention is placed on the top surface of the bottle 4 of, for example, a single bottle filled with the contents, and thereafter, It can be easily mounted simply by applying a pressing force to the top surface 11 of the upper cap 1. The winding step in the conventional step is unnecessary.

The handling of the combination cap of the present invention when the consumer opens the package to take out the filling or recaps and stores the same will be described with reference to FIGS.
First, in order to open the combination cap of the present invention, the user pulls the tab 12a, which is provided at one end of the tamper-evidence band 12 so as to be detachable, and pulls the bridge, so as to tear outward as shown in FIG. And the tamper-evident band 12 is removed from the upper cap, and the lower portion remains as the lower cap cover portion 27 while covering the side wall portion 23 of the lower cap 2, resulting in the state shown in FIG. 3.

Then, in order to remove the combination cap of the present invention from the bottle, pressing the top surface 11 of the upper cap 1 with a finger causes the tamper-evident band 12 to be already removed. 14 presses the vicinity of the center of the top portion 21 of the lower cap.
1 is recessed so as to curve downward. At this time, the side wall portion where the slit is formed with the convex portion 26 as a fulcrum is opened like an umbrella as shown in FIG. 4, and easily disengages from the peripheral groove 41 of the bottle opening 4 with which the curl portion 24 is engaged. The cap can be removed. At this time, the finger has the lower cap cover portion or the upper cap, and the removal operation can be performed safely. In a state where the engagement between the circumferential groove 41 and the curl portion 24 is released, the diameter is set such that the diameter of the side wall portion 23 expanding outward is not extremely larger than the diameter of the lower cap cover portion 27. A gap is provided between the lower cap cover 27 and the side wall 23. Further, the portion of the lower cap cover portion 27 corresponding to the side wall portion 23 may be made thinner, and when the side wall portion 23 expands, the lower cap cover portion 27 may also be expanded.

Remove the cap of the present invention from the bottle 4 again.
When the cap is pushed back near the center with the inner surface of the lower cap 2 in a dome shape, the top portion 21 of the cap of the present invention is restored to the state before opening, and the side wall portion opened in an umbrella shape Since the cylinder 23 is in a cylindrical state, if the outer periphery of the lower cap cover 27 covering the side wall 23 is pressed against the bottle 4, the state shown in FIG. Airtightness is maintained.

[0021]

As is apparent from the above description, the combination cap of the present invention has a tamper-evident band provided on the upper cap made of resin, so that the pill-proof property is maintained and the mischievous opening of the cap is carried out as before. Prevention becomes possible.

Further, since the upper cap is made of resin, it can be removed with a smaller force than when a conventional metal crown is removed, and the most effective thing is to injure a finger. The risk that consumers hate most can be virtually eliminated.

Naturally, the cap can be re-capped, and the cap is attached by engaging with the outer shape of the bottle, so that the inner diameter of the bottle, which tends to vary easily, can be greatly reduced. Since the capping step in the filling step does not need to be tightened just by pressing, the apparatus can be simplified, preventing troubles in the capping step and exerting a side effect on the stability and speeding up of the step. . Therefore, the present invention is extremely significant as a combination cap that can solve the conventional problems.
